Application filed November 6, 1922. Serial No. 599,219.

vTo all whom t may concern.'

Be 1t known that I, LINDSAY C. PnrrNnR, a citizen of the United States, and a resin dent of Johnstown, in the county of Cam-k bria and State of Pennsylvania, have invented certain new and useful. Improvements in Truck Frames; and I do hereby declare the following to be a full, clear, and exact description of my invention, such as will enableothers skilled in the art towhich it appertains to make and use the same.

My invention relates to a truck frame adapted for use in trucks of railway cars, and the principal part-s of this frame are composed of one integral sheet of metal, which is cut or punched in its various portions to the shapes and sizes desired and flanged and then bent around its intermediate portion so as to produce a hollow structure of great strength and rigidity, comprising the various members of what is known as an integral arch bar type of truck side frame.

The plate forming the principal members of my truck frame has flanges vformed, on various of the edges thereof, and in aecordance with my invention some of these flanges are wider than others and adapted to be overlapped, and in certain locations are secured together. by electric or blowpipe welding. This welding is preferably accomplished by providing circular or otherI shaped holes in the outer or in the more accessible one of the overlapping anges and then filling these holes with fused metal, which is fused to both plates in such a way as to firmly secure them together.

The overlapping portions of the` flanges are preferably arranged only on certain of the members and in some cases on certain portions of the said members in such a way as to provide the strength desired in each part with a minimum amount of work and material in accomplishing this. Other members have inturned flanges which are substantially opposite or in line with each other, but with their edges close together or spaced apart as desired.

I prefer to form the pedestal tie bars integral with the rest `of the structure, thus forming a continuation of the bottom arch bar. i

Having thus given a generalydescription of my invention, I will now, in order to make the matter more clear, refer to the annexed sheet of drawings, which kform part of this specication, and in which like characters refer to like parts Y `Figure l is a side elevationof my improved truck frame; Figure 2 is a top plan view thereof; Figure 3 is an end elevation; Figure 4c is a cross sectional elevation taken on the line IV-IV ofFigure 2; Figure 5.

is a central cross section of the bottomarch bar taken on the line V-V of Figure l; Figure 6 is a cross section of the bottom arch bar member taken on the lineVI-VI of Figure l; Figure 7 is a cross section of one of the end members of the frame which rests on the tops of the journal boxes taken on the line VII-VII of Figure l; Figure Y 8 is across section of the inclined tension member taken on the line VIII- VIII of Figure 1; Figure 9 is a partialcross sectional plan through'the lower portions of the truck columns taken on the line IX-IX of Figure 1; looking downwardly; Figure 10 is a cross section of a part of thev pedestal tie bar taken on the line X--X of Figure l, and Figure ll is'a horizontal cross section through the upper portion of one v of the truck columns showing it and the attached column guide plate'V secured thereto taken on the lineXI-,XI of Figure l.
